Foundation repair is the solution to restore stability and protect your property from further deterioration.

Understanding Foundation Repair

Foundation repair is the process of restoring the stability and strength of a building’s foundation that has been compromised. A solid foundation is crucial for any structure as it supports the entire weight and ensures its structural integrity. Various factors can lead to foundation damage, including soil movement, poor construction techniques, excessive moisture, or even natural disasters.

Identifying the need for foundation repair is vital. Look out for warning signs such as cracks in walls, floors, or ceilings, doors and windows that no longer close properly, or even sinking or uneven floors. These signs often indicate underlying foundation problems that should not be ignored.

Assessing Foundation Damage

Before embarking on any repair work, a thorough assessment of the foundation damage is necessary. Professionals skilled in foundation repair conduct an initial inspection to determine the severity of the issue. They employ various techniques such as measuring floor elevations, checking for gaps around doors and windows, and examining the condition of the foundation walls.

These experts play a crucial role in identifying the root cause of the damage and recommending the most suitable repair techniques. Their experience and expertise allow them to accurately assess the extent of the damage and devise an effective plan for restoration.

Foundation Repair Techniques

Foundation repair techniques vary depending on the nature and severity of the damage. Here are some commonly used methods:


Slabjacking, also known as mudjacking, is a technique that involves injecting a mixture of cement, soil, and other additives beneath a sinking or uneven concrete slab. This process lifts the slab back into its original position, providing stability and preventing further damage.


Piering is employed when the foundation has settled or shifted. This technique involves installing steel piers deep into the ground to support the foundation and stabilize it. The piers transfer the weight of the structure to more stable soil layers, preventing further sinking or shifting.

Foundation Underpinning

Foundation underpinning is a method used to strengthen and stabilize a damaged foundation. It involves excavating soil from beneath the foundation and replacing it with stronger materials, such as concrete or steel. This process provides additional support to the foundation, ensuring its long-term stability.

Soil Stabilization

Soil stabilization is often required when foundation damage is caused by soil-related issues, such as expansive clay or poor compaction. This technique aims to improve the soil’s load-bearing capacity and prevent further movement or settlement. Methods for soil stabilization include chemical treatments, soil replacement, or the installation of retaining walls.
